I searched and did not really find anything.
On my half ton the doors will lock from the inside- the key will turn the outer lock mechanism, and slight turns the pin that goes to the handle, but it does not turn enough to unlock the door?
Anyone else have this problem, I have tried lubrication(3/1 oil) and Check alignment and such.

And on my 3/4 ton. When you lock the driver's door it holds it open, not able to latch, flapping like a barn door in the wind kind of open.
The passenger side will lock, but same problem as with the 1/2 ton not enough of a rotation to open the door(without breaking key in lock from turning/bending)

Thanks for the help. Kind of curious and I have put them back to what the book and the pictures in the assembly manual show as correct, maybe I am just overlooking something simple(Other than I am not the best door person)
